\VILLIAM COREY, OF CINCINNATI, OHIO, ASSIGNOR TO THE HALLS SAFE AND LOOK 00., OF SAME PLACE.

SAFE, VAULT, etc.

SPECIFICATION forming part of Letters Patent No. 364,753, dated June 14, 1887.

Application filed April 1, 1887.

To allwhom it may concern.-

Be it known that I, WILLIAM CORRY, of Cincinnati, in the county-of Hamilton and State of Ohio, have invented certain new and useful Improvements in Safes, Vaults, &c., of which struction.

The object of my invention is to provide means by which-the door of safes, vaults, and pneumatic cabinets, or any similar receptacle, can-be forced tightly to its seat, so as to close it airtight when so desired and hold it so until released, and also to start it from its seat when it is desired to open it.

, In the drawings, Arepresents the front of a safe, and B the door of the same. On the door B, I arrange a series of bolts, a and b, the former being arranged to secure the door at its ends and thelatter atits sides. These bolts are held in place near the edges of the door by guides,of which two forms areshowmone form, 0, being simply a flat'strip of metal bent atits center to fit over the bolt, and being secured to the door by bolts orrivets, as shown in Figs. 1 and 2, thereby forming a support and guide for the bolt, which is free to slide to and fro therein. The other form (shown in section in Fig. 3) consists of two brackets, d, secured to the door on opposite sides of the bolt and having a pin, 0, secured therein, said pin passing through a slot in the bolt, as shown in Fig. 3, either form of these guides being used, as preferred.

To the frame or wall of the safe A, along the free side of the door, and also at the top and bottom, I secure brackets I, as shownin Figs. 1 and 2, these brackets consisting of two lugs or plates which project from the face of the safe and have secured therein a pin or bolt, f, on which is mounted an anti-friction roller or sleeve, 0, as shown clearly in Fig. 2, to permit the beveled end of the bolts 1) to be forced in Serial x0. 233.272. (No model.)

behind the pin and roller, and thus crowd or. force the'door inward to its seat as the bolts are moved endwise. On the opposite or hinged side ofthe doorlsecure similar brackets I, the boltand roller, however,being preferably somewhat smaller to work in an inclined slot formed in the outer end of the bolts 1) on that side, as more clearly shown in Fig. 3. This inclined Slot is for the purpose of starting the door from its seat, in case it sticks fast from any cause, and may be used or not, as desired, it being obvious that so far as crowding the door to its seat is concerned the bolts on the hinged side ofthe door may be provided with beveled ends, the same as 011 the opposite side, or as shown in Fig. 2. In order to operate all these bolts simultaneously,Ipivot at the center of the door a disk,C, to which I pivot the inner ends of one pair of end bolts and also one pair of the side bolts, as shown in Fig. 1, they being pivoted to the disk equidistant from its center, so that the rotation of the disk 0 will impart to all the bolts connected to itasimultaneous and uniform movement. To operate the other 7: bolts, b, one pair of which is above and the other pair below the central disk, I pivot to the door two other disks, D, on a central vertical line, one above and the other below the central disk, 0, and connect each by a pivot, 12, to one of the end bolts, a, sothat when the central disk, 0, is rotated to operate the bolts pivoted to it it will also rotate the disks D and thereby operate the bolts 7), pivoted to the latter, and in that way it will be seen that by ro- 8 rating the central disk all the bolts will be moved simultaneously and uniformly, it being understood, of course, that all the bolts will be pivoted to their respective disks at an equal distance from the center, so that each boltshall 0 have the same throw or movement.

1 It is obvious that any desired number of disks D, with their bolts b, may be used by locating them properly and pivoting them to the end bolts, a, in the manner shown; but it will be seldom that more will be required.

In order to impart the necessary force to the disk 0 to force the beveled ends of the bolts in behind the pins f of the several brackets, and thereby wedge or crowd the door into its seat, I fOIlll'Ol] the periphery of the disk 0 a series of teeth, 1, which extend part way around it,

as shownin Fig. 1, and then monnt on the door a pinion, E, so as to engage with these teeth, said pinion being provided with a crank, h, for turning it, asshown. By these means great force can be exerted to thrust the bolts ontward, and the friction that would otherwise be created by their beveled ends bearing against the pins f is prevented or greatly lessened by the anti-friction rollers or sleeves c, and hence the operator can exert such force on the bolts as to crowd the door in against the rubber or other packing ordinarily used to render it airtight.

In order to lock the belts in place and preventthe door from being released until desired, I also cut in the periphery of the disk 0 a series of inclined notches or teeth, 0, and pivot to the door a latch, g, having a series of corresponding teeth or notches, r, to engage with the teeth 0 on the disk 0, as shown, this latch g serving as a pawl to hold or look the disk fast, and consequently to hold the bolts and the door firmly in position. \Vhen it is desired to retract the bolts to open the door, the crank it is pressed in the opposite direction snfficientl y to relieve the strain on the teeth of the catch, when the latter is swung out of contact with the disk and the crank it turned so as to rotate the disk suttieiently to withdraw the bolts, and if the door sticks fast in its seat from any cause the inclined slots 1) will force the door outward 011 that side, thereby loosening it, so it can be readily opened. a

In cases where the door is light, as in pneumatic cabinets, and is not likely to stick in its seat, the inclined slots 12 may be dispensed with, and the bolts on that side he provided with beveled ends, the same as on the opposite side, as it is obvious they will operate to force the door shut just the same, the slots only being required when power is required to aid in opening the door as well as in closing it.

It will of course be understood that when the slots 1) are used it will be necessary to provide the door with the compoundhinges,whieh permit it to move straight into and out of its janibs after being swung to its position, but which, being well k nown, need not be described. Vhen the bolts are provided with the beveled ends at both sides of the door, of course the ordinary form of hinges may be used.

Having thus described my invention,what I claim is 1. The combination, in asafe, vault, orsimilar receptacle, of a series of bolts, a pivoted at their inner ends to a central disk, 0, with two or more sets of bolts, 1), each set being pivoted at their inner ends to separate disks D, said disks being pivoted to the bolts a, and all arranged to operate substantially as shown and described.

2. In combination with the door B, havinga series of bolts applied thereto, said boltshaving their outer ends beveled at the free sides or edges of the door and provided with inclined slots at the hinged side of the door, a corresponding series of brackets, I, provided with anti-friction rollers c for the inclines of the bolts to operate on, substantially as shown and deseribeth 3. The combination, with the bolts (6 b and their operating-disks C 1), arranged as shown and described, of the pinion E, provided with a lover or handle, Ii, and the pivoted lockingleverg, both being arranged to operatein connection with the central disk, 0, substantially as and for the purpose set forth.

In witness whereof I hereunto set my hand in the presence of two witnesses.

WILLIAM COREY.
